Turkish area in grip of national rioting (9)
I believe the answer is:
anatolian
'turkish' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe there's a link between them I don't understand?
'area in grip of national rioting' is the wordplay.
'area' becomes 'a' (maths abbreviation).
'in grip of' indicates putting letters inside.
'rioting' indicates an anagram.
'national' is an anagram of 'anatolin'.
'a' inserted into 'anatolin' is 'ANATOLIAN'.
Can you help me to learn more?
(Another definition for anatolian that I've seen is " From part of Turkey".)
